2-亚胺-9-芳基取代的邻菲啰啉与其铁络合物的制备方法及 其应用
技术领域
本发明涉及2-亚胺-9-芳基取代的邻菲啰啉与其铁络合物的制备方法及其应用。具体的讲是以2,9-二氯邻菲啰啉与芳基硼酸进行偶联反应制备9-芳基取代的邻菲啰啉,经过后续的偶联、水解、缩合等反应最终得到2-亚胺-9-芳基取代的邻菲啰啉,将其与氯化亚铁进行络合反应,可以制备相应的邻菲啰啉铁络合物。该邻菲啰啉铁络合物能够催化1,3-共轭二烯与硅烷的硅氢化反应,得到高烯丙基硅化合物,表现出很高的活性和选择性,特别是对于芳基取代的1,3-共轭二烯的硅氢化,给出优于其它已知金属催化剂的1,2-反马氏加成的选择性,具有很好的应用前景。
背景技术
有机硅化合物是含有C-Si键的化合物统称,由其组成的有机硅材料具有表面张力低、粘温系数小、无毒无味且生理惰性等优点,被广泛应用于航空航天、建筑、化工、食品和医疗等诸多领域[Ojima,I.In The Chemistry of Organic Silicon Compounds,Patai,S.,Rappoport,Z.,Eds.;Wiley:Chichester,U.K.,1989;Vol.1;Chapter 25.],因此对有机硅化合物的合成和应用研究具有重要意义。烯烃的硅氢化反应是最重要、最基础的C-Si成键反应之一,具有100%的原子经济性,为有机硅化合物的合成提供了一种高效的方法。相比于金属试剂与硅试剂的偶联反应来构筑C-Si键的方法,烯烃硅氢化反应具有条件温和、操作简单、原子利用率高等优势,并且可以从大宗工业原料烯烃和硅烷出发合成有机硅化合物,为有机硅化学及有机硅材料的高速发展提供了有力支撑[(1)Marciniec,B.Coord.Chem.Rev.2005,249,2374.(2)Marciniec,B.In Hydrosilylation,AComprehensive Review on Recent Advances,Eds.;Spring,2009.(3)Du,X.Y.;Huang,Z.ACS Catal.2017,7,1227.]。
1,3-共轭二烯作为一类重要的烯烃,由于具有共轭的两个碳碳双键,过渡金属催化其硅氢化反应时存在多种配位和插入方式,导致区域、立体和化学选择性多样,难以调控。
由于过渡金属催化1,3-共轭二烯的硅氢化反应时,容易形成较为稳定的π-烯丙基金属中间体,进而生成1,4-加成产物。目前人们已经发展出很多基于Fe、Co、Ni、Pt、Pd等金属的催化剂,都能实现1,3-共轭二烯的1,4-加成选择性硅氢化[(1)Lappert,M.F.;Nile,T.A.;Takahashi,S.J.Organomet.Chem.1974,72,425.(2)Ohmura,H.;Matsuhashi,H.;Tanaka,M.;Kuroboshi,M.;Hiyama,T.;Hatanaka,Y.;Coda,K.-I.J.Organomet.Chem.1995,499,167.(3)Han,J.W.;Hayashi,T.Tetrahedron:Asymmetry 2010,21,2193.(4)Hilt,G.;Luers,S.;Schmidt,F.Synthesis.2003,634.(5)Wu,J.Y.;Stanzi,B.N.;Ritter,T.J.Am.Chem.Soc.2010,132,13214.]。相对而言,1,3-共轭二烯的催化1,2-加成选择性硅氢化反应更具挑战性,长期缺乏有效的催化剂。直到2014年,Ritter等人发展出环烷基膦双核铂催化剂,利用大位阻配体使金属不容易产生金属-π烯丙基中间体,成功抑制了1,4-加成选择性,才实现了简单1,3-共轭二烯的1,2-加成选择性硅氢化反应[Parker,S.E.;Borgel,J.;Ritter,T.J.Am.Chem.Soc.2014,136,4857],但是这类铂催化剂作用的底物类型十分受限。近年来,人们发展出一系列双齿N,N-配体与铁、钴等丰产金属的络合物,实现了1-芳基1,3-共轭二烯的1,2-马氏加成选择性的硅氢化反应[(1)Hu,M.Y.;He,Q.;Fan,S.J.;Wang,Z.C.;Liu,L.Y.;Mu,Y.J.;Peng,Q.;Zhu,S.F.Nat.Commun.2018,9,221.(2)Wen,H.A.;Wang,K.;Zhang,Y.L.;Liu,G.X.;Huang,Z.ACS Catal.2019,9,1612.]。而三齿N,N,N-配体和钴的络合物则可催化1-烷基1,3-共轭二烯的1,2-加成的硅氢化反应[Raya,B.;Jing,S.;Balasanthiran,V.;RajanBabu,T.V.ACS Catal.2017,7,2275.]。然而,迄今1-芳基1,3-共轭二烯类的1,2-反马氏加成选择性控制仅停留在中等水平[(1)Greenhalgh,M.;Frank,D.J.;Thomas,S.P.Adv.Synth.Catal.2014,356,584.(2)Raya,B.;Jing,S.;Balasanthiran,V.;RajanBabu,T.V.ACS Catal.2017,7,2275.]。
因此发展用于1,3-共轭二烯硅氢化反应的新型过渡金属催化剂,特别是基于丰产金属的催化剂,克服已知催化剂存在的缺点,实现文献中还不能很好控制的1,2-反马氏加成选择性,是本领域研究的重点之一。

总而言之,将2,9-二氯邻菲啰啉与芳基硼酸进行Suzuki偶联反应,后续依次发生Stille偶联、水解、缩合反应可以制备2-亚胺-9-芳基取代的邻菲啰啉;将得到的配体与氯化亚铁进行络合,可以得到不同的邻菲啰啉铁络合物。该新型邻菲啰啉铁络合物能够催化1,3-共轭二烯的硅氢化反应,并表现出以下特点:底物适用范围广,对芳基取代的1,3-共轭二烯、烷基取代的1,3-共轭二烯都表现出较高的催化活性和很高的收率;官能团耐受性好,选择性可控,通过改变配体上取代基,可以分别以很高的区域选择性和立体选择性得到硅氢化产物;特别是对于芳基取代的1,3-共轭二烯的硅氢化,给出优于其它已知金属催化剂的1,2-反马氏加成的选择性。上述特点表明,本发明所提供的新型邻菲啰啉铁络合物催化剂克服了已有技术的缺点,是目前催化1,3-共轭二烯1,2-反马氏硅氢化反应的最高效的铁催化剂之一,具有很好的应用前景。
